A report of a stranger grabbing a student led to lockdowns Thursday morning at two Ventura schools until police determined the report had not been credible.

Students and employees at Balboa Middle School and Mound Elementary School were asked to stay in classrooms as Ventura police investigated the report, which was received at 9:30 a.m., said Cmdr. Tom Higgins. The lockdowns lasted about an hour.

Ventura police said a 14-year-old student walking to school reported he had been approached and grabbed by a someone.
